Kemoeatu was a four-year letterman and three-year starter at Utah. He started 35 of 43 games played in college, finishing his career with 160 tackles and nine sacks. He was suspended by the NCAA for his last college game, the 2001 Las Vegas Bowl, for buying two math books for his younger brother Tevita using scholarship money.[1]

On May 2, 2012, Kemoeatu returned to the Baltimore Ravens. After a one-year hiatus from football, he lost 78 pounds, from 415 down to 337, in a serious attempt to resurrect his career. He wound up winning the starting Nose Tackle job from Terrence Cody, starting 13 games, recording 29 tackles, 1 sack and 1 forced fumble. He also would go on to win his first championship title when the Ravens won Super Bowl XLVII before retiring from football.
